Update:
My scale was repaired by Escali and returned to me. They were quick and easy to deal with.

The scale now reads spot on at 5 grams for a nickel (10 grams for two nickels) and with a 500 gram weight it reads 502 grams, and if one then places the nickel onto the scale with the 500 gram weight it reads 507 grams. And with the 1000 gram weight it reads 1004 grams but add the nickel and it reads 1009 grams.

So it appears to be off by four tenths of a percent...very good for a scale of this type IMHO. I am pleased and can recommend Escali to those interested in a inexpensive kitchen scale.
